"... Abstract. As the reference operating regime for ITER, investigations of the ELMy H-mode have received high priority in the JET experimental programme. Recent experiments have concentrated in particular on operation simultaneously at high density and high confinement using high field side (HFS) pelle ..."

"... The pellet pacing ELM control concept developed at the mid sized tokamak ASDEX Upgrade is considered for the larger machines JET and ITER as well. By driving up the ELM frequency, the ELM size can be reduced and eventually suppressed below a dangerous level. An according pellet injection systems for ..."

28 th EPS Conf. on Contr. Fusion and Plasma Physics, 2001, P3.11 Energy Confinement in Steady State ELMy H-modes in JET

by Max Planck
"... During the last seven years an extensive confinement database has been assembled on JET of steady state ELMy H-mode plasmas. The database was started under the JET Joint Undertaking and has been continued under EFDA with the addition of a further 200 pulses. In this paper the database is used to ass ..."

"... Abstract. The poloidal field (PF) coil system on ITER, which provides both feedforward and feedback control of plasma position, shape, and current, is a critical element for achieving mission performance.
